Question: Is it wrong to have a romantic relationship with a married person? In Ayn Rand's novel Atlas Shrugged, Dagny Taggart had an affair with Hank Rearden, knowing that he was married. How should those actions be judged in real life? Clearly, Hank's cheating was dishonest and wrong. Was Dagny wrong to pursue the affair? What should she have done instead? Or, imagine that Dagny didn't know that Hank was married until after they'd slept together. What should she have done in that case upon finding out the truth? Should she stop the affair?
